Proponent's argument for bill:(US Fish and Wildlife Service statement on NAWCA): The North American Wetlands Conservation Act of 1989 provides matching grants to carry out wetlands conservation projects in the US, Canada, and Mexico for the benefit of wetlands-associated migratory birds and other wildlife. The Standard Grants Program supports projects that involve long-term protection, restoration, and/or enhancement of wetlands and associated uplands habitats. The Small Grants Program supports the same type of projects but project activities are usually smaller in scope, [under] $75,000.

Opponent's argument against bill: (Heritage Foundation 2008 statement on wetlands enforcement):
The 2006 Supreme Court ruling in Rapanos v. US restricts the EPA from setting a strict and expansive definition on what classifies as a wetland and what can and can't be regulated. The EPA defines wetlands as "including swamps, marshes, bogs, and similar areas", but it is more complicated than that. For instance, in the Rapanos case, Rapanos' land was 20 miles away from navigable water, but under the EPA's unrestrained definition, the term "navigable water" was also broadly defined. Having such an expansive definition would allow the EPA to run wild with environmental regulation. A less expansive definition may beget more uncertainty as to how the EPA should regulate wetlands, but it will also lead to more careful deliberation rather than unwarranted regulations.
